- Don Flack: [Mac arrives at the crime scene] Hope you skipped breakfast.
- Mac Taylor: That bad?
- Don Flack: Worse.
- Don Flack: Turns out Richards was a rising star on the cage fighting circuit.

- Mac Taylor: I know you terrorized Ryan Richards and his wife for years. I also know you weren't man enough to take credit for it.
- Adam Ross: Mac. Look, I know I've called you a genius before, but this time, I really mean it.
- Mac Taylor: Why is that?
- Adam Ross: Ryan Richards tried to contact his wife.
- Mac Taylor: How?
- Adam Ross: As you expected, he's smart enough to know that we'd be monitoring phone calls and e-mails, so he tried a more antiquated form of communication.

- Aaron Collins: It was just a picture.
- Mac Taylor: "Savor the victory now, 'cause you'll be dead by morning." That's more than a picture, that's a death threat.
